Your ARV tells you what you can spend on rehab. Not the other way around. I see investors fall in love with a renovation plan and then try to force the numbers to work. That's backwards. The numbers come first. The renovation plan serves the numbers.
The 70% Rule (And Why It Still Works)
The classic formula: Maximum Purchase Price = (ARV x 70%) - Rehab Cost
On a $280K ARV property with a $50K rehab:
- Max purchase: ($280K x 0.70) - $50K = $146K
This leaves $84K for your profit, closing costs, holding costs, and agent commissions. Tight but workable.
Now watch what happens when the rehab creeps to $65K:
- Max purchase: ($280K x 0.70) - $65K = $131K
You need to buy $15K cheaper to make the same margin. In a competitive market, that might mean losing the deal.
And if the rehab hits $80K:
- Max purchase: ($280K x 0.70) - $80K = $116K
The deal might not exist anymore at that purchase price.
How ARV Should Drive Your Rehab Plan
Before you plan a single renovation, run the deal math:
- Determine ARV from comps
- Apply the 70% rule (or your preferred formula)
- Back into your maximum rehab budget
- Design the renovation to fit that budget
If your max rehab budget is $50K, don't plan a $65K renovation and hope you can "save" on materials. Plan a $45K renovation with $5K contingency. Stay inside the math.
Finish Level by ARV Range
The ARV determines what finish level the market demands:
Under $200K ARV: Builder-grade finishes. LVP flooring. Laminate countertops. Budget cabinets. Clean and updated but not fancy.
$200K-$300K ARV: Flip-grade finishes. Shaker cabinets. Granite or quartz countertops. LVP or engineered hardwood. Subway tile backsplash.
$300K-$500K ARV: Upper flip-grade. Soft-close cabinets. Quartz countertops. Hardwood flooring in main areas. Tile in bathrooms. More trim detail.
Over $500K ARV: Approaching custom. Higher-end materials, more design elements, professional staging likely needed.
Over-improving for the ARV range burns money. Under-improving leaves money on the table. Match the rehab to the market.
The Rehab Budget Breakdown by ARV
| ARV | Typical Rehab Budget | Rehab as % of ARV | |---|---|---| | $150K | $20K-$30K | 13-20% | | $200K | $30K-$45K | 15-22% | | $250K | $35K-$55K | 14-22% | | $300K | $45K-$70K | 15-23% |
If your rehab is creeping above 25% of ARV, check your scope. You might be over-improving or the deal math might not work.
How Weekly Draws Protect Your Deal Math
Weekly draws give you real-time budget tracking. If your $50K rehab is at $25K after Week 4 of a 10-week project, you know you're trending over budget with 60% of the work still ahead.
That early warning lets you:
- Adjust the remaining scope to stay on budget
- Evaluate whether the deal still works at the higher rehab cost
- Make informed decisions instead of discovering the overrun at project end
